Subject: [PATCH 1/2 v2] staging: dgnc: remove redundant NULL check for brd
Date: Fri, 27 May 2016 10:42:22 +0900 [thread overview]
Message-ID: <20160527014142.GA32739@SEL-JYOUN-D1> (raw)
the "brd" value cannot be NULL in dgnc_finalize_board_init().
Because "brd" as a parameter of this function was already
checked for NULL.
the dgnc_finalize_board_init() as a static function was called
only from dgnc_found_board() function and brd->magic value
was assigned once in dgnc_found_board(). So it doesn't need to
check for DGNC_BOARD_MAGIC value.
